UNITED STATES PATENT OFFICE.

PATRICK M. EGAN, OF COUNCIL BLUFFS, IOWA.

VENTILATOR.

To all whom it may concern:

Be it known that I, PATRICK M. EGAN, a citizen of the United States, residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Ventilators, of

which the following is a specification.

This invention relates to ventilators.

One object is to provide a ventilator constructed and arranged to provide for a complete ventilation of railroad cars or buildings.

Another object is to provide a ventilator of the character stated embodying such characteristics as to provide for a vacuum in the car as air rushes through the ventilator.

A still further object lies in the provision of a ventilator so constructed and arranged that it may be effective regardless of the direction in which a train may be moving and effectually carrying out the purposes of completely ventilating the interiorof the ear and preventing the possibility of dirt, cinder and other foreign matter finding its way through the ventilator into the car.

A further object I have in view is to permit the deflectors to automaticallyposition themselves according to the direction of movement of the car or other vehicle and to provide not only for a perfect ventilation but also to prevent dust, cinder or rain entering the vehicle.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and particularly pointed out in the pended claims, it being understood that changes may be made in the proportions, material, size and minor details without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawings :*Figure 1 is an elevation of a portion of a car illustrating my device in elevation attached thereto. Fig. 2 is a top plan view, certain of the interior parts hemg shown in dotted lines. Fig. 31s a longitudinal, horizontal, sectional view of the in vention. Fig. 4 is an end view. Fig. 5 is a transverse, sectional view. Fig. 6 is a detailed plan view illustrating the deflectors. Fig. 7 is a detailed side view of the deflectors and the frame in which they are mounted. Fig. 8 is a detail elevation of the deflector blades viewing the same at an angle from Fig. 7. Fig. 9 is an elevation of a portion of a car Specification of Letters Patent.

Serial No. 341,593.

illustrating my invention partly in full and dotted lines in a stateroom or berth of a Pullman car, and Fig. 10 is a sectional view illustrating the modified form shown in elevation in Fig. 9.

Referring now to the accompanying drawings and more particularly to Figs. 1 to S inclusive, the reference character 1 indicates the upper portion of a car or a portion of any other suitable structure provided with an opening 2 preferably surrounded by a rectangular or other shaped frame 3 to which the casing 1 is secured instead of directly to the car or other structure. This peculiar mounting of the casing prevents marring of the structure to which it is secured. If desired, a screen 2 may be disposed over the opening 2, as indicated in Fig. 2.

The top, bottom and outer side faces of the casing 1 are flared outwardly at each end, as at 4, while the inner face of said casing preferably extends at each end slightly beyond the outer extremity of said flaring por tions 4. The inner face of the casing at each end is directed inwardly toward the opposite end and toward the outer side of the casing, as at 5. The inner extremity of these inclined portions 5 are bent, turned or otherwise shaped to form flanges 6 for engagement with the corresponding sides of the aforesaid frame 3 to be secured thereto for the support of the casing 1.

Reference to Fig. 5 will disclose that the top of the casing 1 extends along the upper outer face of the frame 3 to be secured thereto, while the bottom of the casing is provided with a gutter whose inner wall 7 engages the outer face of the bottom of the said frame to be secured thereto. As clearly shown in this same figure of the drawings, the wall 7 extends from the outer edge of the frame to the bottom of the casing 1 near the outer face of the latter. The opposite ends 8 of this wall 7 are inclineddownwardly into meeting engagement with the bottom of the casing 1 at the base of the flaring portions 4 of the latter. As the result of the inclined parts 5 of the bottom of the casing and the inclined parts 8 of the wall 7, the interior of the casing is of less diameter at its center than at its ends for a purpose presently understood.

Arranged within the frame 3 is a series of fixed slats 9, each arranged upon a downward incline with its inner longitudinal edge 10 lying in a plane opposite to the plane of i the outer longitudinal edge 11 thereof. These slats are fiXed and need not necessarily be as wide as the depth of the frame 3.

A strip of suitable material 12 may be secured to opposite, upper, inner sides of the frame 8, to each of which is engaged the pintle 13 of the end deflectors 14, there being an intermediate swinging deflector arranged to cooperate with the end swinging deflector 14 across the frame intermediate the ends of the latter. The lower ends of the deflectors are inclined, as shown, to correspond to the inclination of the aforesaid wall i 7 (see Figs. 4 and 6).

In Fig. 2, the arrow indicates the direction in which the train is moving. Under these conditions, the deflectors are swung by the wind upon their pivots to a point controlled by the stop 16, and in order that all deflectors may be thrown simultaneously to assume the same planes, I provide each deflector with a perforation 17 engaged by the link connections 1.8.

If the train should be moving in the opposite direction the deflectors would be swung automatically into directly opposite planes and limited in the latter swinging movement by the sto 19.

From the foregoin it will beseen t at the wind passing throu'g h the contracted intermediate portion of the casing will operate the deflectors automatically and create a vacuum in the car to cause the hot or impure air therein to be drawn outwardly therefrom between the slats 9 of the frame 3.

The slats 9 are arranged at an angle to the plane of the deflectors, in view of which, a cinder, dirt, or rain in order to enter the car would have to travel against the laws of gravitation. Aside from the contraction at the center of the casing incident to the inclined parts 5 and the wall 7 with its inclined portions 8, the deflectors still further decrease the area intermediate the ends of the casing. The result is that the air passing through the ventilator and over the lattice work resulting from the slats 9, together with the deflectors projecting from the frame, a strong vacuum 1s rovided for.

n Figs. 9 and 10, I illustrate my improved ventilator in cooperation with a state or drawing room, in which it will be seen that the opening 2 communicates with the air space 20 of the car and that in this space 20 there is disposed a pipe 21 connected at its lower end to a flaring intake member 22 whose lower end opens over the radiating tubes 23 within the car. In this pipe 21 I 7 provide a damper 24 for obvious purposes. Aside from the feature just referred to there ing pipes and passing between the inner and outer walls of the case up to the bottom of the ventilator in the clearing deck thus causing a vacuum in the conductor pipe 21 between the heater and ventilator acting entirely under natural laws. This particular system is designed for taking up the excess heat caused by over heating systems and especially will this system be of'advantage in the early spring and fall.
